AOB mitral cell tufts are electrically remote from the soma. A, Reconstruction of an AOB mitral cell having six tufts terminating in five glomeruli. The inset shows convergence between tufts 2 and 3. B, Data from simulations showing the decay of voltage changes from tuft to soma as a function of the frequency of a sinusoidal input (current injection). Each line represents the voltage attenuation from a single tuft of the reconstructed cell shown in A plotted against the frequency of the sine wave. C, Histogram of passive attenuation from tuft to soma for 17 tufts from four reconstructed cells simulated in Neuron.
